photodiode
Sign in to saveA photodiode is a semiconductor diode sensitive to photon radiation, such as visible light, infrared or ultraviolet radiation, X-rays and gamma rays. It produces an electrical current when it absorbs photons. This can be used for detection and measurement applications, or for the generation of electrical power in solar cells. Photodiodes are used in a wide range of applications throughout the electromagnetic spectrum from visible light photocells to gamma ray spectrometers.
AI overview
A photodiode is a semiconductor device that converts light and other radiation into electrical current when it absorbs photons. It's useful for detecting and measuring light across a wide range of types—from visible light to X-rays—and is also used to generate electrical power in solar cells.
